6 Claims. (Cl. 21 1-=-55) This invention relates to display racks and more particularly to display racks of the wire frame type designed to be folded or collapsed for shipment or storage.

In the past, when a customer came into a store to buy a greeting card, a package of wrapping paper, ribbon, or other type wrapping component, the chances were that a sale was made only for the particular item requested since each of the items was displayed in a different part of the store. No association was made in the customers mind between his desired merchandise and the other wrapping components so that he might buy some of the other associated items at the same time. The collapsible rack disclosed in this patent application makes it possible for the store owner to display greeting cards, wrapping paper, ribbons, etc., all at the same time on the same rack. When the customer comes in to buy one item, he or she will also think of buying other items at the same time due to this association of wrapping components on a common display rack. When the customer shops from this rack, it will be more convenient for him and will result in increased sales for the store.

It is highly desirable that a merchandise display rack be capable of carrying the mechandise for which it was designed without danger of giving way or of swaying and bending. At the same time, the rack should be capable of low cost manufacture, light in weight and foldable into a compact bundle for shipment or storage. The present invention, therefore, includes among its objects to provide a wire rackor display stand which is: strong and sturdy and is braced against both vertical and lateral stresses or strains that may be imposed thereon in supporting relatively heavy quantities of merchandise; foldable or collapsible into a compact bundle; and designed for ease and economy in manufacture and particularly for manufacture by the electric welding process.

Another object of the present invention is to provide in a display rack of the type described, having parts swingable from a normal merchandise supporting position to a collapsed position, means to detachably unite or latch the parts together in the normal merchandise supporting position. Means may also be provided for latching or uniting the parts together in the collapsed position.

Another object of the present invention is to provide in a display rack of the type described made of lengths of wire or bars welded together.

Other features of this invention reside in the arrangement and design of the parts for carrying out their appropriate functions.

Other objects and advantages of this invention will be apparent from the accompanying drawings and description and the essential features will be set forth in the appended claims.

Fig. -8 is a vertical sectional view taken along the line 8--8 of Fig. 3 showing the supporting legs of the top rack in their collapsed position in solid line and in their normal merchandise supporting position in dot-dash line when thetop rack serves as a counter display; while Fig. 9 is an enlarged partial perspective view taken from the back of the top rack of Fig. 3 with rolls of Wrapping paper shown therein in solid line- The composite collapsible merchandise display rack of this invention for displaying gift wrapping component is shown in Figs. 1 and 2 of the drawings. The rack consists of a base rack, generally indicated at 10, a top rack 50 and a basket 90. These units are made of lengths of wire or bars welded together by one of the common welding processes, such as electric, gas, etc. Welding. This rack is especially designed for displaying wrapping paper, ribbon, tags and seals to satisfy Christmas gift wrapping and everyday gift wrapping needs. This will be set forth in greater detail later in the specification.

The base rack 10, as seen in Fig. 1, consists of a back framell, having two side frames 12, 12, one pivotally or swingably mounted on each side of the back frame. A plurality of shelves 13 are also pivotally mounted to the back frame 11.

The upright back frame 11 of base rack 10 in Fig. 1 has a periphery or border defined by a one piece length of wire 14. The wire length 14 has a substantially inverted U-shape to define the sides and top of the back frame 11. The lower end of the vertical portions of the wire length or bars, composing the legs of the inverted U- shape, define substantially V-shaped legs 15. Each end of wire length 14 defines one of the legs 15, as seen in Fig. 1. Substantially horizontal wire lengths or bars 16, 17, 18 and .19 are vertically spaced on the wire length 14 and substantiallyparallel to each other. Each of these bars or wire lengths 16, 17, 18 and 19 is welded to both of the vertical legs of the wire length 14. The wire lengths or bars 16, 17 Each is bent into the form of an eye at its ends. A first set of eyes 16a, 17a and 19a at corresponding ends of bars 16, 17 and 19 respectively are in vertical alignment while a second set of eyes 16b, 17b, and 1% at the opposite ends of the bars are also in vertical alignment. The horizontal connecting member 21 is welded to each of the ends of wire length 14 (inner ends of legs 15) and to each of the vertical legs of the wire length 14. A diagonal brace 20 is welded to horizontal wire lengths or bars 16, 17, 18, 19 and 21. This diagonal brace unites the other Wire lengths of the back frame together and helps prevent any needless distortion of the back frame.

Two side frames 12, 12 are provided in base rack 10. One is pivoted on each of the opposite lateral sides of the back frame 11. Since both side frames areidentical,

' only one will be described. Fig. 2 shows the side frame 12 most clearly. A one-piece length of wire 22 is bent to definethe three sideso'r the periphery of the side frame. Each endof the wire length 22. is bentlupwardly and inwardly in the plane of the side frame to define a substantially ll-shaped leg 23 at the bottom end of the side frame. This wire length 22 has a vertioa'lbar 22a which is pivotally and vertically slidably mounted in one of the sets of eyes located on corresponding ends of the wire lengths or bars 16, 17 and 109. Downwardly and forwardly inclined cross barsZd, 25, 26 and 27 are'each welded to the vertical legs or bars of wire length 22. It should be noted that downwardly and forwardly extending portion 22b of wire length 22 and cross'bars 2S and 27 are located" adjacent the mounting eyes of the back frame. This construction prevents vertical relative movement .taking place between the back and sideframe. Even though cross bars 25 andl2'7 are shown inEig. 2 as being mounted between the eyes'17a and 1%, it should be apparent that instead the eyes 170! and 19a could be mounted between the cross bars and vertical relative movement would still beprevented. Downwardly and rearwardly inclined braces 28, 29, 3t and'31 are .provided. Each of these braces islwelded to two or more of the cross bars 24,25,26 and 27.

A plurality of shelves 13 are provided in the base rack 10 of Fig; l. These shelves are in vertically spaced relationship with each other. Since each shelf'13 is identical, only one will be described. Each shelf 13 is pivotally mounted'on the front side of the back frame by rearwardly extending spaced eyesfisurrounding one of the horizontal wire lengths or bars 17, 18 or 19. A one-piece length of wire'32 isbent to define the three sides or periphery of .a' shelf. The side portions of this wire length 32 :are downwardly inclined from the horizontal wire length or bar of the back frame and then extend upwardlyperpen'tiicu'lar .to the main portion of the shelf to form a'bent-upforward edge, as seen in Pig. 1. Each end of the wire length 32 has an eye formed therein to encircle the wire. length or bar on the back frame and pivotally mountthe shelf thereon. A plurality of horizontal bars 34 are welded to the side portion of wire length 32. A substantiallyL-shaped cross bar 35 is welded to the center of each horizontal bar 34 and to the center of the front edge of wire length 32 and also has an eye 33 formed at the upper end thereof. Other cross bars 35a are spaced parallel to cross bar 35 closer to the side of the shelf and are welded to the horizontal bars34. This construction provides a strong? shelf.

.Mea'nsis provided to detachably engage the side frames to thejsh'elf :in normal merchandise supporting position to form a n'gid merchandise display rack. One of the horizontal, bars .34 of each shelf 13 has a laterally disposed hook 36 :at each end. This hook 156 is adapted to engage the cross bar 25, 26 or 27. When the hooks 36 of each shelf have securely engaged the cross barsof the side frames, the base rack 16 will form a rigid merchandise display rack. This rack may also be collapsed as shown in Figs.'6 and 7 of the drawings. The shelves 13 are pivoted or swung upwardly and the side frames 12 are swung'rearwardly until the rack reaches its collapsed position with the shelves folded into contiguous position with the front side of the back frame 11 and the side frames swung around until they touch or are in contiguous-position with the back side of the back frame, as shown in solid lines in Figs. 6 and 7.

The top rack 50 is best shown in Figs. 3, 4, 5, 8 and 9. This rack has a downwardly and forwardly extending display portion having a plurality of large display pockets 51 arranged in step relation and small display pockets 51a arranged along the back of the rack to support aplurality of articles or packages for display. Thisstep relationship forms a saw tooth profile below the display portion, as seen in Fig. 5. Each large display pocket 51 is adapted to support a flat pack-age, as seen in dot-dash linein Figs. 4 and.5, and each small pocket 51a is'a'dapted to support a tubular roll of material in upright'position notedvthat the rolls in small pockets 5100f. Fig. 9 arealso in the rear large pocket 51'.

The display portion is supported by a substantially rectangular frame surrounding it. The frame has a wire length 52 bent into rectangular form with the ends of the wire length welded together to form a closed rectangular member. A horizontal bar 53 is located below and parallel to the front horizontal portion of the rectangular wire member 52, and these members are held in this relationship by vertical bars 54, 54, each bar 54 being welded to the front horizontal portions of rectangular wire member 52 and the horizontal bar 53. A U-shaped member 55 lies in a plane slightly inclined-to the horizontal and has its ends attached to the opposite sides of rectangular member 52 by welding. Vertical bars 56, 56 are welded to the rear horizontal portions of rectangular member 52 and U-shaped member 55 at opposite ends of the back of the rack, as seen in Figs. 3 and 5.

Means are provided on the rack-'50 to support the display portion either on base rack 10 to formv a composite rack or on a flat surface, as seen in Fig. 5, so that-rack 50 may serve as a counter display.

The means to detachably mount the top rack 50'on the base rack 10 consists of hooks on the top rack-Siladapted to engage the wire lengths or bars of the base rack 10. A hook 58 is formed at the top of each vertical bar 56 ofthe top rack 50, and this hook58 engages over wire length .or bar 16 of the back frame 11 of the base rack 10, as seen in Fig. l. A hook 57 is formed at each end of horizontal bar 53 at the front lowerend of the top rack 50. Hooks 57 engage over the downwardly and forwardly inclined cross bars 24 of the side frames 12 of the base rack 10, as seen in Fig. 2. Hence, the top-rack 50 with its hooks 57 and 58 engage the back frame 11 and side frames 12 of the base rack 10 to retain these frame membersin their. normal, forwardly disposed, merchandise supporting position and to support the top'rack 50 on the base rack 10.

Means is also provided to-support the top rack 50 on a flat surface so that it may serve as a counter display, as seen in Figs. 5 and 8. Rearwardly extending spaced bars 59 and 60 are each pivoted at one end adjacent the front lower-end of the display portion, one being mounted adjacent. each of the hooks 57 on the horizontal bar 53. The bars .59 and 6t convergeslightly toward the rear of therack. Eyes 5% and 6011 on the respective bars 59 and 60 encircle the horizontal bar 53 to provide the pivotal connection. The distal ends of the bars 59 and 60 respectively. are each provided with hooks-59a and 60a respectively. A substantially vertical U-shaped member has a substantially horizontal cross bar 61 and vertical legs 62 and 63 at the opposite ends of the cross bar6l. .Thelegs Y 62 and 63- are substantially parallel to each other. The upper ends of the legs 62-and 63 respectively have eyes';62a.and.63a surrounding and pivotally mounted on the rearhorizontal portion of U-shaped member55 adjacent'theupper rear end of the display portion. -A horizontalicross bar64 connects legs 62 and 63 and is welded theretoto form a more rigid structure. The top side of horizontal cross bar 64 engages in the loops of the hooks .59aand 60a when the rack 50 iserected for counter'display, as shown in Fig. 5 andin dot-dashline in Fig. 8. A latch means connects the rearwardly extending bars 59 and 60 adjacent their distalendand resiliently urges cross bar 64 into the loops of hooks 59a and 60a by. pushing .upward on the bottom side of bar 64. Thismeans consists, of a cross bar or chevron-shaped bent wiremember 65 having an end welded to each of the rearwardly .extending space bars 59 and 60. Hooks 59a and 60a and member 65 could engage cross bar 61 instead of cross bar 64, if desired. The above structure comprises the rear support of rack "50. The front support, on the right in Fig. 5, will be described hereinafter.

The .rack 50 may be collapsed for shipment or storage,

as seen in solid line in Fig.8. The substantially U-shaped member composed of members 59, 60 and 65 and the substantially U-shaped member composed of members 61, 62, 63 and 64 may be folded into the saw tooth bottom profile of the display portion, as seen in Fig. 8. The sec ond U-shaped member is swung or folded in first and then the first U-shaped member is folded in underneath the display portion and the chevron-shaped member 65 resiliently latches under the bar 78 of the display portion to be described in more detail hereinafter. The legs 62 and 63 and the spaced bars 59 and 60 straddle the sides of the display portion when they are in collapsed position, shown in solid line in Fig. 8.

The display portion comprises three rows of large pockets 51, each row being downwardly and forwardly inclined, as seen in Figs. 3, 4 and 5, and adapted to support upright flat objects or packages. Each pocket 51 comprises an inverted U-shaped wire member 70 forming a back support and having substantially vertical legs 71 and 72. Legs 71 and 72 are not absolutely vertical but have a slight rearward inclination. Legs 71 and 72 have a forwardly bent lower end portions 73 and 74 respectively which are welded to the corresponding vertical legs 71 and 72 of the next pocket downwardly and forwardly inclined below the described pocket. The legs 71 and 72 of the rearmost pocket in each of the three rows are welded to the rear horizontal portion of rectangular frame member 52. The forwardly bent portions 73 and 74 of the lower pocket in each row are bent upwardly to form portions 73' (Figs. 1 and 3) and 74' (Figs. 1, 3 and 8) and welded to the front horizontal portion of rectangular member 52 and to horizontal bar 53. A horizontal bar 54a is welded to vertical bar 54 at the left in Figs. 1 and 3 and to the upwardly bent portion 73' between member 52 and bar 53. A similar horizontal bar 54a connects the upwardly bent portion 74' and vertical bar 54 at the right in Figs. 1 and 3. The forwardly bent portions 73 and 74 of each lower pocket, as seen in Fig. 5, forms the front support when rack 50 serves as-a counter display.

The display portion also comprises a plurality of smaller pockets 51a placed along the upper rearward edge of the display portion to support tubular members in vertical relationship, as seen in Fig. 9. An endless wire member 75 is bent to form two horizontal bars with each end of said horizontal bars connected by a substantially C-shaped section of wire. The center of each 0- section is. welded to the rear horizontal portion of the U-shaped member 55. A plurality of C-shaped sections 76 are spaced along the horizontal bars of the endless member 75 and have their ends welded to the horizontal bars. The two horizontal bars of the members 75 lie in a plane substantially parallel to the plane formed by the rear horizontal bar of rectangular member 52 and U- shaped member 55, and these two planes form the front and rear boundaries of these small pockets 51a. It should be noted that the forwardly bent portions 74 and 73 of the legs of the rearmost larger pockets 57 described in the previous paragraph extend from front to rear between these two planes. The leg portions 73 and 74 of the rearmost pocket 57 in each row and the substantially C-shaped sections 76 are equally spaced so that they may support rolls of wrapping paper in substantially vertical relationship at the back of the rack 50 approximately parallel to the plane of inverted U-shaped member 70. Hence, the forwardly bent portions 73 and 74 serve as a bottom of the rearmost large pockets 51 at the upper rear portion of the display portion and serve as spacers to form some of the small pockets 51a. A U-shaped member 77 has its legs welded to the C-shaped end sections of member 75. The horizontal bar of the U-shaped member 77 is spaced between the two parallel planes heretofore described and serve as a bottom for the pockets 51a adapted to hold the tubular rolls of wrapping material.

i and lforwardly inclined divider bars ,7

I as seen in Fig. 3, separate the three rows of downwardly and forwardly inclined pockets. Each divider bar 79 has a downwardly inclined leg at the forward end which is welded to horizontal bar 53 and to the forward horizontal bar portion-of rectangular member-.52 and a rearward vertical leg welded to the horizontal bars of endless member 75. l

Each-of the larger pockets has an ornamental piece of metal 80 attached to the horizontal bar of the inverted U-shaped wire member 70. This ornamental piece of met-a1 may contain indicia or other appropriate display, material. The inverted U-shaped wire member 70 of each of the rear pockets has a chevron-shaped piece of bent wire welded to the horizontal portion and the vertical legs 71 and 72 for additional ornamentation.

A wire basket 90 may be detachably mounted on the lower front surface of top rack 50, as seen inFigs. 4 and 5. The basket comprises a top frame 91 made of a piece of wire bent into a rectangular shape and having its ends welded together to form an endless member and to form the mouth of the basket. U-shaped members92 formrthe front, back and bottom 'of'the basket and are welded at each end to the top frame 91. Horizontal connecting members 93 extend fromleft to right in the basket and arewelded to the U-shaped mem bers 92 to assimilate a basket weave on the front, back, and bottom of. the basket 90. A sine curve shaped wire design 94 is welded to the U-shaped members 92 on the front of. thewbasket and has downturned endsto complete the'design. End sections 97 are made of Wire and simulate a basket weave and are welded to .U-shaped members 92 and the horizontal connecting members 93 of the front, back and bottom of the basket. Each end section 97 contains a sine curve shaped design 95 having upturned ends andbeing welded to the rest of the end section. The basket has a plurality of ornamental pieces 98 inside the rear wall which correspond in function to the ornamental pieces 80 previously described. Two hooks 96 are welded to the horizontal connecting members 93 of the back of the basket so that the basket 90 may be detachably mounted on the front horizontal bars 54a between vertical bars 54 and outside the outermost upwardly bent portions 73 and 74. Bars 54 and portions 73' and 74' horizontally align basket 90 directly in front of top rack 50.

'It should now be apparent that the composite rack of this invention has many uses and is especially designed to display wrapping paper, seals, tags and ribbons needed in wrapping Christmas packages and everyday gift packages. The composite rack made of the base rack 10 and the top rack 50 may or may not include the basket 90, whichever is desired. Fig. 1 shows them without the basket while Fig. 2 shows them with the basket. The top rack 50 may also be used as a counter display without the base rack 10, as seen in Figs. 3, 4, 5 and 8. Basket may be attached to the top rack 50 when used as a counter display if desired, as seen in Figs. 4 and 5. The base rack 10 may hold on shelves 13 such articles used in wrapping as boxes of seals, tags and ribbons, flat packages of wrapping paper, and boxes of enclosure cards to accompany the gift. Top rack 50 may hold a plurality of flat packages of wrapping material in the large pockets 51, and if desired, tubular rolls of wrapping paper may be supported in the small pockets 51a in the rear of the top rack to make an attractive background for the flat packages of wrapping paper. A sign may also be attached to the upper rear portion of the top rack 50, if desired, so that it projects above the top of the packages of wrapping paper and is easily readable from the front of the rack. The basket 90 may support boxes of ribbon, seals, tags and enclosure cards, comm-only used in wrapping packages.

The rack, regardless of which of the above forms it may take, is advantageous to both the store owner and the customer. .Thegstore owner willobtain a. larger volume of s'ales. since all the'jgift wrapping accessories are displayed on the-one rack and T the customer will generally .buy'..all of ,his; gift wrapping essentials at the storeleven though he had in mind to buy'only the one item.
